Extract references from academic papers

To extract references from academic papers, you can follow these methods depending on the format of the document and the tools you’re using:

---

1. From PDF Files (Manual or Semi-Automated)

If you have a PDF of an academic paper:

Manual Extraction:

• Scroll to the end of the paper (usually under “References” or “Bibliography”).

• Copy and paste the reference list into a document or text editor.

Semi-Automated Tools:

• Use PDF extraction tools like:

  • Adobe Acrobat: Use the “Export PDF” to convert to Word or text.

  • PDFTables: Converts PDF to Excel or CSV for easier parsing.

  • Grobid (open-source): Parses and extracts metadata and references from scientific PDFs.

---

2. From Online Databases

Many journals and academic databases (e.g., PubMed, Springer, IEEE, JSTOR) provide downloadable citations in various formats:

• BibTeX

• EndNote

• RIS

• Plain Text

Look for a “Cite This” or “Export Citation” button on the article page.

3. Using Reference Management Tools

Programs like:

• Zotero

• Mendeley

• EndNote
  Allow you to:

• Import entire papers (PDFs)

• Automatically extract reference metadata

• Export the bibliography in your desired format

---

4. Using Programming Tools (for batch processing)

If you have many papers and want to automate reference extraction:

Python Libraries:

• PyMuPDF or pdfminer.six for reading PDFs

• Grobid-python (wraps Grobid for easier access)

• Regex patterns to extract references (based on patterns like numbers, authors, years)

python
CopyEdit
import fitz  # PyMuPDF

doc = fitz.open("your_paper.pdf")
text = ""
for page in doc:
    text += page.get_text()

# Extract references section using simple pattern
import re
match = re.search(r"(?i)referencesn(.+)", text, re.DOTALL)
if match:
    references = match.group(1)
    print(references.strip())

---

5. From LaTeX or HTML Sources

If the paper is available in LaTeX or on arXiv:

• References are typically inside .bib or begin{thebibliography} tags.

• You can extract directly or use tools like BibTeX Parser.

---

6. Online Extraction Tools

• Citation Gecko

• Connected Papers

• Research Rabbit

• Semantic Scholar: Extracts references and citations per paper with links.
